Two versions of the robot were used during Lost in Space filming a "hero robot" costume worn by Bob May, and a static, "stunt
robot" prop that was used for distant or hazardous shots. Both versions fell into disrepair after the series, but these have
since been discovered and restored. The "hero" is privately owned by TV and film producer Kevin Burns, who commissioned a
replica in the early 1990's for touring and conventions. The "stunt robot" is in storage at the Science Fiction Museum and Hall
of Fame in Seattle, Washington.
